Question

$20 ° C$ less than the present temperature. Give the corresponding Expression.

Open in App

Solution

Let the present temperature be $x ° C$
So, $20 ° C$ less than the present temperature would be $20$ subtracted from $x ° C$ which is $X - 20 ° C$
Hence the required expression is $X - 20 ° C$
